A fly in my beer!
One day an Englishman, an American, and a Canadian walked into a pub together. The proceeded to each buy a pint of Molson Canadian. Just as they were about to enjoy their beverage three flies landed in each of their pints.
The Englishman pushed his beer away from him in disgust.
The American fished the offending fly out of his beer and continued drinking it as if nothing had happened.
The Canadian picked the fly out of his drink and started shaking it over the pint, yelling...
"SPIT IT OUT, SPIT IT OUT YOU BASTARD!!!"
